HZG series rotary drum (high/low temperature) dryer

Short Description:

HZG Rotary Drum Dryer is a cylindrical body whose main body is slightly inclined and can adjust the rotation speed within a certain range. The wet material is fed into the cylinder by the feeding machine, and the plate feeder of the inner cylinder is uniformly turned. The material is evenly distributed and dispersed in the dryer and is in full contact with the hot air (co-current or counter-current) passing through the drum to speed up dry heat transfer and mass transfer. In order to achieve the purpose of drying. The device can use various forms of copy board to adapt

Works

Wet material from the dryer is put into one end of the inner cylinder cloth copy turning plate reader, the homogeneous distribution of material in the dryer with the dispersion, and contact and full flow (countercurrent) hot air, speed up the drying mass Heat, spread to the driving force. During the drying process, the material can be regulated to move to the other star discharge valve of the dryer to discharge the product under the action of the tilting plate and the hot air flow.

Adapt To The Material

◎ chemical, mining, metallurgy and other industries large particles, dry material than the major, such as: mines, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulfate.

◎For the drying of powder and granular materials with special requirements, such as: HP foaming agent, distiller's grains, light calcium carbonate, activated clay, magnetic powder, graphite, and dregs.

◎Requires low-temperature drying, and large batches of continuous drying materials.

Performance Characteristics

◎ Rotary dryer has a high degree of mechanization and a large production capacity.

◎ The resistance of the fluid through the cylinder is small and the function consumption is low.

◎ The adaptability to material properties is relatively strong.

◎ Stable operation, low operating cost, and good product drying uniformity.
